I hope it's okay to reply to a two-year old thread, but this is still the primary Google hit when trying to figure out the Random Logo feature for the PocketBook, and it's not covered in the manual at all. I thought I'd add my experience in 2022 so others who find this on Google can save the couple hours it took me.

I have an InkPad 3 Pro. I made the mistake of trying to convert and save the images myself in Photoshop CS6, but even after multiple attempts to save with the right bit depth, colors, and resolution, they just wouldn't work. The device would see the images (they appeared in the Gallery app, and also in the list of options for Boot Logo), but couldn't display them. They were blank.

I should have just followed alexxxm's instructions verbatim above, and I'd suggest anyone else coming across this thread to do the same first. I downloaded and installed ImageMagic v7 on Windows 10, and placed the images I wanted to use (saved as Grayscale in Photoshop, as jpg, in the 4x3 aspect ratio) in a folder with nothing else. I ran cmd.exe as Administrator and navigated to the folder with the images, then used the command below. Like alexxxm mentioned, the syntax is SLIGHTLY different, but only barely! You just have to add "magick" to the beginning. So, the below should work:

Code:

magick mogrify -resize 1404x1872 -background white -gravity center -extent 1404x1872 -format bmp -colors 16 *

It will convert every image in the folder, and save BMP versions of all of them to the same folder. Add those BMP files to your device, and it will work! If you set it to random logo, it will cycle through them.

And I can confirm that for the InkPad 3 Pro, the folder you put the images in is the same: /system/logo/offlogo

But, even if you have "show hidden files" turned on, you might not be able to see the system folder when you navigate to the Inkpad 3 in Windows Explorer. It is hidden. What you can do is click the address bar and manually add "\system" then press enter (for example, if the PocketBook is set as the E drive, it should read "E:\system"). Then you will be in the folder.

Hope this helps someone!

P.S. Don't try to run the legacy ImageMagick v6. At least for me on my set-up, it threw multiple errors that v7 did not relating to support for image formats.
